ATLANTA -- Brad Baca is still undefeated as a head coach after his Pittsburg Pirates rode a fast start and took down Atlanta, 40-14, Friday night at Rabbit Stadium.

Pittsburg, which dropped its first four games of the 2014 season, improved to 4-0 for the first time since 2011. The Pirates have defeated their four opponents by a cumulative scoring margin of 89 points, a year after being minus-121 through four weeks.

Pittsburg coasted into halftime with a 33-0 lead on Atlanta (2-2) and never looked back.

Pirates senior running back Tray Walker did most of Pittsburg's damage, rushing for 167 yards and two touchdowns on 19 carries. Elijah Boyd added 56 yards and a pair of scores on 16 carries.

Pittsburg quarterback Brian Baca completed 12 of 19 attempts for 119 yards and a touchdown. Damien Porter caught six passes for 51 yards and a score, and tossed an 11-yard touchdown to Deldric Shields.

Each team returns to action next Friday night. Pittsburg plays at Mount Vernon, while Atlanta travels to Liberty-Eylau.
